Description

Technical Field

[0001] The invention relates to the technical field of permeability detection, in particular to a concrete permeability detection device. Background Art

[0002] During the construction process, in order to ensure the overall quality and strength of the building, before pouring concrete, the construction party needs to select specimens from the batch of concrete to make concrete test blocks and send them to professional testing agencies for professional testing. Only after the quality and strength of the test blocks are fully qualified, the batch of concrete can be officially put into use. Concrete permeability testing is an extremely important item among many concrete tests.

[0003] Concrete permeability testing is to determine the anti-seepage grade of concrete samples by adding water to the concrete samples and measuring the seepage water. When testing, the concrete samples need to be sealed on the outside of the middle section to fit the inner wall of the mold to prevent water pressure from seeping out from all sides. However, the sealing brought by this sealing structure is relatively poor. The existing testing equipment can only test one group of concrete samples at a time. At the same time, due to insufficient water pressure or insufficient water volume, water may enter the concrete but not be enough to seep out of the concrete. At this time, due to the lack of data provided by the seepage water, the personnel cannot make an accurate judgment on the test results. Even if water seeps out, it may be affected by random variables, resulting in inaccurate test results. Summary of the invention
